Reviewed by Robert Pritchett
Introduction
Although Ruby is an easy language
to learn, in the heat of action you may find that you can't remember the
correct syntax for a conditional or the name of a method. This handy pocket
reference offers brief yet clear explanations of Ruby's core components, from
operators to reserved words to data structures to method syntax, highlighting
those key features that you'll likely use every day when coding Ruby.
Whether you've come to Ruby because
of the Rails web development framework --Ruby's killer app -- or simply because
it's a relatively clean, powerful and expressive language that's useful for a
lot of applications, the Ruby Pocket Reference is organized to help you find
what you need quickly. This book not only will get you up to speed on how Ruby
works, it provides you with a handy reference you can use anywhere, anytime.
